I think it does. I would very much like to get rid of sockaddr at all, but there is no reason to why we wouldn't be able to have a thin layer which accepts a traditional INET/INET6 type of sockaddr to a AF_NAME socket and then simply "under the hood" convert it to something more From the user perspective, it would be a completely ordinary socket call with a different address family. The current API suggestion (which will most likely be heavily modified) allows the responder to accept from any name, which I think would be fine for the "blank name" scenario. Conceptually, it would be as you describe it: legacy-sockaddr (IP) + an ignored (empty?) name. // Javier
